Decimal point nonsense

Again the promised software upgrade has mangled the decimal point on your answers to the fourth iClicker question. (The other question answers were whole numbers or alphanumeric.) The answer for the fourth question was "-1.7" and many of you sent that. However the software recorded that as "-1.=" which looks heinous.

However, I did several practice sessions today at home and figured out the correct answer and all the incorrect answers. I have uploaded exactly what my system recorded; now you know how to interpret it. So all the garbled data has been graded by me accurately.

Some of you got partial credit for leaving off the negative sign on the fourth question.

I am uploading a few sets of iClicker data right now. More tomorrow.
